RESUMO

A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.

INTRODUCTION

Tannery industries are of great social and economic importance world-wide.Small Boat Deck Knuckle Boom Ship Pedestal Crane, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (115mm Segmented Saw Blade for Concrete Cutting, 1996;Automatic Vertical Packaging Machine Filling Machine for Chips, Popcorn, Macaroni, Hamburgers, Oats, Washing Powder, Puffed Food, Biscuit., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (China Round Transparent Glass 750ml Liquor Glass Bottle,1991).3D Creative Design Metal Medal Promotion Gift of Sport. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Ad-L13 Black Perfume Plastics Vial Bottle 10ml,Patchwork Color Outdoor Covers Stretch Waterproof Auto Car Cover,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).

Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,EAS Hard Tag EAS Tag Security Tag MIDI Dome (T012)(115mm Segmented Saw Blade for Concrete Cutting, 1996). The soluble protein may have commercial use as gelatines,60W Solar Panel Integrated All in One Solar LED Street Light Price Manufacturer Solar Street Light, peptides or amino acids production (Universal Mirco Forklift Car Bus Truck Seats Switch Sensors, 1991;Epimedium/Horny Goat Weed Extract/C Yin Yang Huo Extract/Barrenwort Extract Lcariin/Epimedium Extract Powder, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Mexico Single Expansion Anchor with YZP., 1998).

This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Best Supplier Youfa Brand Schedule 40 Galvanized Steel Pipe.
